Any info on the surname Kormes

My father-in-law Wasiliy Kormes born in Romania in 1921 came to England we think after the war 1939-45.He married in England in 1954.We have no details of which town or village he was born.Wasiliy's father was called George and he was a farmer, found this info on the marriage certificate here in Bradford, England.Has anyone any idea if the surname could have been spelt differently and changed when Wasiliy came to England?Has anyone any idea how we can trace the family history?
